If you've ever owned an in-ground swimming pool, it was a fun place for family recreation, a great place to entertain friends and an ideal opportunity to teach the kids how to swim. Your pool may also have become the prime play area for neighborhood children, allowing you to keep a close eye on your children, since they were at home. Now you have another opportunity to reconsider your options, please consider the following....


Hot Tub Spa, Swim Spa and Pool Considerations:

You may be considering the purchase of a swimming pool to provide fun for your children, so you can teach them to swim and you can keep an eye on them at home. An Atera AnyTemp® Spa, Swim Spa, Hot Tub or Pool will provide these benefits, year round outdoors in any climate, at a fraction of the cost of an only seasonal in-ground pool.

• Maintenance heating and cooling costs for a pool can be very expensive. Without heating, and without chilling a pool, the seasonal window of time for comfortable use is only a few months, even in the hot climate of Phoenix, Arizona!

• For several months during the summer, in hot and humid climates, pools, hot tub spas and swim spas are often too hot to be enjoyable.

• Hot Tub temperatures are easy to regulate in the winter, since all other brands of hot tub spas and swim spas only heat the water. However, soaking in hot water, often exceeding 100° F in hot tubs, with no option for reducing the tenperature during the hot and humid summer months is not pleasant for most people.

• In the summer, ambient air temperatures, UV rays and kinetic energy generated by motors and pumps heat hot tubs and swim spas even with the heaters have been turned off. Some brandsclaim they have a “cool summer mode” but without actively actually cooling the water it's not possible to cool the water below average daily ambient air temperatures.

• Hot tub spas have a High Limit Safety Sensor designed to disable the entire hot tub spa if the water temperature gets too hot (105°F - 110°F). A hot tub spa cannot then be reset and become operational until the water temperature is reduced below 104°F. Try twenty bags of ice for today, what about tomorrow?

• In hot climates, this high limit safety switch feature often renders hot tub spas useless during the hottest months unless ice is used to temporarily reduce the water's temperature, allowing you to reset the system. What about tomorrow? More ice?
